What's slowing my fretting hand down here?

I’d like someone who knows better than me to tell me what I’m doing wrong here.

What I am trying to play is an ascending shred line in the 3NPS minor scale root position. I am warmed up. My fingers immediately recognize the shape, but the way that they progress up in it is obviously very inefficient. It’s uncomfortable, especially for my back, but I know of no better way to do it. I’ve tried several different fretting postures, and nothing provides the comfort and efficiency that I need to be able to play this simple thing. It feels like putting together an impossible puzzle.

Additional notes:

  • The D and G strings are where I start locking up badly.
  • I’ve never been hung up on things like this with my picking hand. My picking hand learns quick while my fretting suffers.
  • Descending lines are easier for me.
  • Here’s a video of me actually playing well. I was tense, but I was able to get a take of me playing cleanly: https://youtu.be/jQEOn3c9-WU?si=Wx6APUVjYPPSzehv
